EVALUACIÓN DE LA CASCARILLA DE HIGUERILLA COMO POSIBLE ADSORBENTE DE CONTAMINANTES FENÓLICOS EN FASE ACUOSA

Abstract

Con el propósito de brindar valor agregado a la cascarilla de higuerilla como bio - adsorbente para el tratamiento de aguas residuales, se realizaron ensayos preliminares de retención en fase acuosa de fenol y p-nitrofenol a una temperatura de 25°C, considerando factores tales como concentraciones iniciales (30 – 60 ppm) y pH; los datos obtenidos fueron analizados de acuerdo a los modelos de Langmuir y Freundlich observando cantidades retenidas que van desde 7 hasta 15 ppm del compuesto en el material sin tratamiento alguno.

An investigation was initiated to evaluate the potential use of castor seed shell as a bio–adsorbent for was tewater treatment to reduce the adverse environmental impacts. Preliminary tests were conducted in aqueous phase retention phenol and p-nitrophenol at a temperature of 25° C, considering factors such as initial concentrations (30 - 60 ppm), pH and contact time. The data obtained were analyzed using Langmuir and Freundlich models, which showed 7 to 15 ppm of phenol and p-nitrophenol were retained of the compound in the untreated material.
